SI-IOE-SCRAPING DEVICE.

Specification of Letters Patent.

Patented Mar. 28, 1911.

Application filed February 28, 1910. Serial No. 546,450.

To all whom it may concern:

Be it known that I, JOHN C. OLIVA, a citizen of the United States,residing at Marengo, in the county of Iowa and State of Iowa, haveinvented a certain new and useful Shoe-Scraping Device, of which thefollowing is a specification.

lhe object of my invention is to provide a shoe scraping device ofsimple, durable and inexpensive construction that may be formed completeof a single piece of material and that may readily and easily be driveninto the ground and that is provided with means for limiting thedownward movement of the scraper into the ground and that is alsostrongly and firmly braced and reinforced.

A further object is to provide a device of this kind that may be formedcomplete of a single piece of sheet metal in such a manner that themetal will have a double thickness throughout the entire device and alsoin such a manner that it is strengthened and reinforced at the variouspoints where the greatest strain or weight occurs.

My invention consists in certain details in the construction of the shoescraper whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claims and illustrated in theaccompanying drawings, in which:

Figure 1 shows a front elevation of a device embodying my invention madeof cast metal. Fig. 2 shows a side elevation of same. Fig. 3 shows aview similar to Fig. 1 illustrating a device embodying my invention madeof a single piece of sheet metal. Fig. 4 shows a side elevation of same,and Fig. 5 shows a plan View of a blank piece of sheet metal cut out asrequired to form my improved shoe scraper. The dotted lines in saidfigure show the lines along which the sheet metal is folded.

Referring to the accompanying drawings, the head of the device isindicated by the numeral 10. Its top central portion is preferably fiatat 11 to form a scraper for the sole of a shoe. At the sides of the part11 are the upwardly extended lugs 12 which preferably extend inwardly attheir upper ends toward the center of the part 11 for the purpose ofscraping a shoe above the sole. At the bottom of the head 10 is a flange13 arranged in a substantially horizontal position and below the flange13 is the body portion 14 which is preferably tapered to a point at itslower end. On one side of the body portion lt is a reinforcing rib 15also tapered to a point at its lower end, the upper end of said ribbeing formed integral with the flange 13.

In the form of the invention shown in Figs. 1 and 2, there is also a rib16 extending through the flange 13 to the central portion of the part 10to strengthen and reinforce the rib and the part 10.

In the form of my invention which is made complete of a single piece ofsheet metal the blank for forming the shoe scraper is cut out in themanner shown in Fig. 5. In this form of my invention the part aboveground comprises a body portion 17 provided with an opening 18 soarranged that when folded along the dotted lines 19, there will be adouble thickness of the parts corresponding to the part 10 as shown inFig. 1. Furthermore at one end of the part 17 is an extension 20 havinga slot 21 and two side flaps 22, and in the opening 1.? is a sidereinforcing flap 28 for purposes hereinafter made clear. The part of thedevice to be inserted below the ground comprises a body portion 2-1tapered to a point at its lower end. In folding the part- 24, I firstbend the sides thereof along the lines 25 to form a double thickness ofmaterial and I then bend it alongthe lines 26 so that the remainingparts outside of said lines 26 constitute ribs or flanges 27. At theupper ends of the ribs or flanges 27 are the lugs 28 which are soarranged as to fold along the lines 29 upwardly and toward the bodyportion of the device above ground and said parts 28 constitute theflanges for limiting the down ward movement of the device into theground. After the parts that go below the ground have been folded thenthe head of the device is doubled along the line 19 and the slot 20 willreceive the upper end of the reinforcing ribs 27 to hold them togetherand then the flanges 22 are folded over back of the scraper to firmlyhold the parts together. Then the part 23 is folded over the flatsurface which constitutes the portion of the foot scraper that receivesthe sole of the shoe to thereby strengthen and reinforce the device atthis point where the greatest wear takes place. It also prevents the twoparts of the head from spreading away from each other so that on accountof the peculiar construction and arrangement of the sheet metalportions, the entire device may be made of a single piece of sheet metaland there is not only a double thickness throughout the entire devicebut in addition to this the parts are all strengthened and reinforcedwhere it is necessary to hold them together to make a firm, strong anddurable device out of a single piece of comparatively thin sheetmetal.

In the form of theinvention shown in Fig. 3, I have provided at the topof the scraper the outward projecting lugs which may be usedin scrapingmud from a shoe and I have also rounded the body portion of the scraperat 31 for convenience in scraping shoes.

It is obvious that with either form of my improved scraper the devicemay be readily and easily driven into the ground and its downwardmovement into the ground would be limited by the flange. It will befirmly and securely held in its position in the ground on account of theshape of the part flange being designed to limit the downward movementof the device in the ground.

2. In a device of the class described, a single piece of sheet metalcomprising a body portion tapered to a point at its lower end and havingits sides doubled over adjacent to each other at the longitudinal centerof the device and having its side edge portion projected away from thebody portion and parallel with each other, lugs at the upper ends ofsaid side edges extended toward the body portion of the device andoutwardly away from each other to form a flange to limitthe downwardmovement of the device into the ground, the head of the scraper beingdoubled along a horizontal line and folded over, said folded over partbeing provided with an extension having a slot therein to receive theprojecting edges of the lower portion of the device and also having lugsat its sides folded over the back of the body portion of the device tofirmly unite said parts, said folded over portion of the top of thedevice being also provided with a flange folded over the top edge ofboth por tions of the upper part of the device to form a roundedstraight edge for scraping purposes and to strengthen and reinforce thescraper at the top.
